 a plurality of facets, wherein the plurality of facets includes at least two different facet sizes. 
 
 
     
     
       2. The arrowhead of  claim 1 , wherein the tip is detachable from the body and the tip has a longitudinal length. 
     
     
       3. The arrowhead of  claim 2 , wherein the aperture extends through the entire longitudinal length of the tip. 
     
     
       4. The arrowhead of  claim 2 , wherein the tip is threaded onto the body. 
     
     
       5. The arrowhead of  claim 1 , wherein the tip includes a third tip point and a second cutting edge is disposed between the second tip point and the third tip point. 
     
     
       6. The arrowhead of  claim 5 , wherein a third cutting edge is defined between the third tip point and the first tip point. 
     
     
       7. The arrowhead of  claim 1 , wherein the plurality of facets are arranged radially about an outer circumferential surface of the tip. 
     
     
       8. The arrowhead of  claim 1 , wherein each facet includes a first beveled portion, a second beveled portion, and a planar portion disposed between the first and second beveled portions. 
     
     
       9. The arrowhead of  claim 1 , wherein the body includes a plurality of grooves defined in the body that are oriented along the longitudinal length of the body, and wherein an edge of each of the plurality of blades is disposed in a respective one of the plurality of grooves. 
     
     
       10. The arrowhead of  claim 9 , wherein each of the plurality of facets lies radially between two adjacent grooves of the plurality of grooves. 
     
     
       11. The arrowhead of  claim 1 , wherein there are an equal number of blades and tip points, and wherein there are at least as many cutting edges as tip points. 
     
     
       12. The arrowhead of  claim 1 , wherein the body defines an internal cavity and an electronic component is disposed within the internal cavity. 
     
     
       13. The arrowhead of  claim 12 , wherein the electronic component is a laser diode, the laser diode arranged so that the laser beam emitted by the diode projects forward from the arrowhead through the aperture in the tip, the laser beam being coaxial with the center axis of the tip. 
     
     
       14. An arrow system, comprising
 an arrow shaft comprising a first end and a second end; and 
 an arrow head coupled to an end of the arrow shaft, the arrow head comprising:
 a body; 
 a plurality of blades extending outwardly from the body; and 
 a tip extending forwardly from the body, the tip defining a center axis and including:
 a first tip point; 
 a second tip point; 
 a first cutting edge disposed between the first tip point and the second tip point; 
 an aperture defined in the tip along the center axis of the tip; and 
 a plurality of facets, wherein the plurality of facets includes at least two different facet sizes. 
 
 
 
     
     
       15. The arrow system of  claim 14 , further comprising a lightable nock coupled to the second end of the arrow shaft. 
     
     
       16. The arrow system of  claim 14 , wherein the tip is removable from the body and is coupled to the body with screw threads. 
     
     
       17. The arrowhead of  claim 14 , wherein the tip is removable and defines a longitudinal length, and wherein the aperture extends through the entire longitudinal length of the tip. 
     
     
       18. A hollow tip and multi-point broadhead, comprising:
 a body comprising a first end and a second end; and 
 a removable tip portion, including a first end, an opposing second end, a longitudinal length extending between the first and second ends and a center axis along the longitudinal length, 
 wherein the first end of the tip portion is coupled to the body, 
 wherein an aperture is defined in the tip portion, the aperture extending inwards from the second end of the tip portion towards the first end of the tip portion and along the center axis, and 
 wherein the tip portion includes:
 a first tip point; 
 a second tip point; 
 a first cutting edge disposed between the first tip point and the second tip point; and 
 a first facet defined in the tip portion having a radiused first facet surface contour. 
 
 
     
     
       19. The arrow system of  claim 18 , wherein the tip portion is coupled to the body with screw threads.
